Retelling A Video Hello, i want to retell the video, after i see it. Geothermal power plants usesuperheated fluids from the earth’s geothermal resources to generate electricity. Thenatural heat of the earth creates geothermal resources. This heat comes from moltenrock, called magma, located at the earth’s core deep below the geothermal resource.Over thousands of years, rainwater seeps through cracks in the earth’s surface anscollects in underground reservoirs. The magma heats the water until it becomes asuperheated fluid. To reach the superheated fluid, wells are drilled 5,000 to 10,000feet below the surface of the earth.

a process that turns the geothermal superheated into steam while removing solidsfrom it. The steam is used to drive a turbine and generated electricity. Under its ownpressure, superheated fluid from the geothermal resource flows naturally to thesurface through production wells. As the liquid flows the surface, the presseuredecreases, causing a small portion of the fluid still within the well to sepaarater or“flash” into steam. At the surface, the superheated fluid and steam mixture flowsthrough surface pipelines and into a wellhead separator. Inside the separator, thepressure of the superheated fluid is reduced.

The flash process continues in the flow- pressure crystallizer. The remainingfluid is again flashed, this time at a lower pressure, to produce low pressure steam.All of the low pressure, standard pressure, and high pressure steam is delivered aturbine. The fluid that is not flashed into steam flows into the reactor clarifiersystem and is then returned to the geothermal reservoir through injection wells.

Turbine are the primary piece of equipment used to transform geothermal

energy into mechanical energy. The force an energy in the steam is used to spin theturbine blades. The turbine turn a shaft directly connected to an electrical generator.An electrical charge is created when magnets rotate within the generator.

Geothermal energy is a sustainable resource because, with proper

management, a geothermal resource can remaina renewable source of energy.However, it is possible to deplete the geothermal resource by removing fluid fasterthan it can be naturally replaced. At this stage, it’s possible to recover minerals fromthe geothermal fluid before it’s injected back into the earth. This condensed fluid,along with the fluid that did to steam, is injected back into the undergroundreservoir. Magma naturally reheats the fluid so it can be used again.
